You can fly around with the cursor keys and mouse (Babylon default behaviour). Then hit the ‘a’ key to trigger an animation (and an error – after which you can’t fly around any more!) [Edit – fixed thanks to the peeps over at the HTML5 game devs forum]

The whole reason I wanted to do this was for fun, and to try and provide a visualisation for this 3d dogfight Code puzzle, but someone beat me to it, so now it’s just for fun.
